Duh, my mistake. "-r" was already used in rrdtool graph so the option to use is different: "-S 1800" or "--step 1800". > Probably an old rrdtool version: 1.0.42. Would that matter much in how > rrdfetch and rrdgraph get their data? Probably not, but I am not sure. The docs for 1.0.49 say: "By default rrdgraph calculates the width of one pixel in the time domain and tries to get data at that resolution from the RRD. " I always try to match the amount of time with the amount of pixels. Maybe you can do the same and see if that helps. > Thanks, I'll set up a cron job for every week for the next year or so, > that'll do fine. Make sure to check that it works.
